Letters Patent No. 101,713, dated April 12,1870.

IMPROVEMENT IN EARNING-MILLS The Schedule referred to in these LettersPatent and making p'u't' 01 the same To all whom it may concern Be itknown that I, BARNARD Oonrm'rn, of Nor- .walk, in the county of Huronand State of Ohio, have Like letters of reference refer to like parts inthe several views.

Objective.

The nature of this invention relates to so hanging the shoe of afanning-mill that the rear and front end thereof shall have an equal andcommon vibratory movement.

It also relates to the manner of arranging the sieves and grain-boardsof the shoe so that much of the chaff is separated from the grain beforethe application of the blast, as hereinafter more fully described.

A further improvement consists in the construction of the hopper so thatits sides shall have an equal angle, said hopper being framed into thetop of the mill, and with it forming a constructive part thereof,instead of being made separate therefrom.

It also relates to the construction and adaptation of a journal-seat forthe axle or shaft of the fan, so that t forms an angle-iron, forsecuring the sides of the mill to the frame thereof, all of whichishereinafter more fully described.

Descriptive.

Fig. 1 represents a perspective view of the mill, of which A is thefan-case thereof, and B the section, in which is arranged the shoe andsieves, the general shape, size, and construction of which are like thisclass of mills in ordinary use.

The shoe 0, fig. 5, in which the several sieves are arranged, issuspended in the body of the mill in front by a pair of stirrups, D, theupper end of which is attached to the side of the mill, whereas-thelower end is connected to the bottom of the shoe. A pair of stirrups, E,corresponding to these, suspends the rear end of the shoe.

The shoe is braced longitudinally by diagonal straps F, which, and alsothe stirru'ps, are indicated by the dotted lines a b.

It will be obvious that. in suspending the shoe in the manner abovedescribed, not only the toe or front of the shoe will be allowed avibratory lateral movement, but also the heel or rear end will have thesame action.

The ordinary way of attaching the shoe is to pivot the rear end, andhang up the front end, the consequence of which is' that the frontendonly has a direct vibratory action, whereas the rear end swings aroundupon its pivot with but little movement in a lateral direction, and notsufiicieut to shake up the grain in order that it may run through thesieves.

This difficulty is avoided by hanging the shoe as above described, asboth ends are shaken alike, and the grain thereby caused to pass throughthe sieves much more readily and with greater uniformity than in the oldway.

To facilitate the passage of the grain to the hopper, an agitator, G,figs. 4 and 5, is attached to the rear end of the shoe.

Said agitator consists of a series of fingers, 0, projecting upward fromthe shoe into the hopper, which, as said shoe vibrates, they alsovibrate with it, thereby constantly agitating the grain in the throat ofthe hopper, and preventing it from lodging therein.

The sieves are arranged in the shoe in the order as follows:

The first or uppermost one, H, fig. 4, extends back to the rear of theshoe; therefrom directly under the throat of the hopper. Mills asordinarily made have a grain-hoard immediately under the throat,.insteadof a sieve, upon which the grain falls; thence onto a coarse sieve orseries of sieves. In this way all or mostof the small foul st-ufl runsthrough the sieves with the grain, and is either separated by beingblown out of the pan, or by the use of a number of screens introducedfor that purpose, the' result of which is that much grain is blown outwith the foul stuff and last, and more or less of the foul stuff goesthrough. along with the grain. This objection is avoided by allowing thegrain to fall directly from the hopper onto the screen, through whichmost of the foul stuff and small seeds will fall onto the seed-boards Land J, fig. 2, immediately under the sieve H, and to whiclr'it forms aclose tight bottom. The seeds, &c., escape from under the screen Hthrough openings on each side of the shoe at the points e, fig. 5, andare conveyed into the SGQdrbOX H by conductors K, attached to thooutsides of the shoe. By this means the grain falls over the front endof the sieve H, and is exposed tothe wind as it falls down upon thelower range of sieves, with much less foul stuff to be blown out by thefan, therefore requiring less wind to clean the grain and labor to runthe mill.

A further improvement consists in constructing the hopper M, fig. 2, soas to form permanent-1y a part of the machine, and notdetachabletherefrom. The two lateral sides of the hopper are secured in apermanent manner to the sides of the mill; so also is the rear end N,whereas the front end 0 is'movable therein, grooves being cut in theinner sides of the wall, in which the end is fitted so as to slideupward or down ward, for opening or closing the bottom or throat of thehopper, as may be required.v

It will be observed that each of the two opposite sides of the hopperare arranged at an equal angle, the purpose of which is to allow thegrain to plow down and out of the hopper equally from all sides;therefore it is less liable to lodge upon the sides of the hopper, andwill be fed more-evenly than if the sides were of unequal angles.

A further improvement consists in the journal-box, in which runstheshaft of the fan. Said box consists of along sleeve, P, fig. 1, in whichis fitted and runs the journal of the shaft.

From the inner end of the sleeve projects at right angles a lug, Q,which, together with the sleeveforms an angle-iron.

By the use of this peculiar angle-iron and journalbox, the side of themill isfirmly secured to the front 'of the frame, as shown in fig. 7, inwhich R represents a section of the side of the mill; Q, the lug of theiron; and A, the post.

In said figure it will beseen that the lug embraces I is the side of themill,'and'is secured thereto by a screw or bolt, 11, whereas the sleevepart of the box is'bolted to the part as seen in fig. 6.

It will be obvious that, by this means, the shaft ofthe fan is not onlyprovided with a journal-box, but that the side of the mill and port areconnected in a most substantial manner, thereby makin g the machinestronger and more durable.

C'lmlms.

What I claim my improvement, and pray maybe granted to me by LettersPatent, is-

1. The angle-iron and journal-box 1?, when combined and applied tothepurposes in the manner substantially as specified.

, 2. The auxiliary screen H and conductors K, in combination with theshoe G, agitator G, and hopper, substantially as and for the purposedescribed.

3. The arrangement of the agitator G and shoe 0, in combination with thehopper M, when said hopper is so constructed as to form a part of theframe-work of said mill, and provided with the slide 0, and groo e forthe same in the sides of the frame, as and for the purpose substantiallyas set forth.
